Given Input Data is 903, 570, 146, 320

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 146 is 2 x 73

Prime Factorization of 320 is 2 x 2 x 2 x 2 x 2 x 2 x 5

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(903, 570) = 171570

GCD(903, 570) = ( 903 x 570 ) / 171570

GCD(903, 570) = 514710 / 171570

GCD(903, 570) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 146

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 146) = 438

GCD(3, 146) = ( 3 x 146 ) / 438

GCD(3, 146) = 438 / 438

GCD(3, 146) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 320

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

GCD(1, 320) = 320 / 320

GCD(1, 320) = 1

GCD of 903, 570, 146, 320 is 1
